Configurable Analyzer Manager version and improved CA result parsing

Summary

Add a user-configurable scanner binary (Analyzer Manager) version override in the plugin's Advanced settings, update the default AM version to 1.30.1, and rework Contextual Analysis SARIF output parsing to use a rules-based approach that reads applicability status from rule properties instead of relying on result kind/suppression alone. Informational SARIF results are now filtered out across all scanners.

Changes

• Configurable AM version: Added scannerBinaryVersion field to ServerConfigImpl (with builder, equals, hashCode), GlobalSettings, and the Advanced tab UI (JFrogGlobalConfiguration.form/.java). The download logic in ScanBinaryExecutor resolves the effective version (user override or default 1.30.1) and re-downloads when the configured version changes.
• Rules-based CA parsing: ApplicabilityScannerExecutor now overrides parseOutputSarif to determine applicability from rule.properties.applicability (applicable / not_applicable), deduplicates rules (preferring applicable over not_applicable), and creates notApplicable warnings via a new factory method on JFrogSecurityWarning.
• Filter informational results: Both the base ScanBinaryExecutor.parseOutputSarif and the new CA parser skip results where kind == "informational".
• PypiScanner fix: Replaced deprecated PyPipEnvPackageManager with PyPackageManager.
• Bug fix: ServerConfigImpl.equals now uses Objects.equals for externalResourcesRepo (was ==).
• Misc: Updated plugin verifier to 1.400, added name field to Rule, removed unused artifactoryPublish blocks from test Gradle files, updated tests for the new parsing logic.

Testing

• Updated ScanBinaryExecutorTest.testSarifParserApplicResultsWithRulesBasedParsing to verify the new rules-based CA parsing (2 results: 1 not-applicable, 1 applicable).

• Added testSarifParserSkipsInformationalResults with a new secrets_with_informational_output.sarif fixture.

• Updated Gradle test fixtures and assertions for compatibility.

• All tests passed. If this feature is not already covered by the tests, I added new tests.
